SHUTTLE-CUTTING MACHINE.

Specification of Letters Patent.

Patented Jan. 26, 1915.

To all whom it may concern:

Be it known that 1, ROBERT N. ALLEN, a citizen of the United States, residing at Methuen, in the county of Essex and State of Massachusetts, have invented a new and useful Improvement in Shuttle-Cutting Machines, of which the following is a specification.

This invention relates to certain new and useful improvements in shuttle heading machines, and relates more particularly to a machine of the type generally indicated which is used to hollow-out shuttle heads.

The object of the invention is to provide a machine of the type indicated, which more expeditiously performs the required opera tion, and which can be easily and quickly operated so as to increase the output.

Further, the invention aims to provide means which positively holds the shuttle against movement during the cutting action of the machine, and one in which various adjustments can be easily and quickly obtained, in setting up the machine for operation on a shuttle.

Still further, the invention aims to provide means which will automatically return or restore the shuttle to a position out of engagement with the cutter, upon completion of the cutting action.

In the drawings Figure 1 is a front side elevation of the machine. Fig. 2 is a right side elevation thereof. Fig. 3 is a top plan view.

In proceeding in accordance with this invention, a vertically adjustable guide knee 1 is provided on which a cross slide 2 is mounted and adjustably moved by means of a hand wheel 3. A clamp screw 1 is employed tosecure the cross-slide 2 to the knee 1 in its adjusted position. A post 5 slides vertically in a bearing 6 and has connected thereto a base plate 7 which has an extension 7 the extension having spaced depending ears 8 which receive therebetween a lug 9 formed on the upper end of a guide rod 10, to which ears the lug is pivoted by a pin 11. Rod 10 has a sleeve thereon which slides in a bearing 11 carried by the cross slide 2, the ends 12 and 13 of the sleeve being provided with adjustable stop collars 14 and 15 respectively, which engage the respective top and bottom faces of the bearing 11. A rod 16 is pivotally connected to the lower end of guide rod 10 and may be actuated by a foot treadle 16. A U-shaped flat spring 17 is secured at its free ends to the cross slide 2 and to the extension 7 of the base plate 7, in order to restore the base plate 7 and connected parts to normal position after same has been depressed by the rod 16 for the purpose to be later herein set forth. Rigidly secured to the base plate 7 is a head 18 of U-shape which has bearings 19 and 20 at its free upper ends. A housing 21 is mounted to aline with the space between said free ends of the head 18 and has a shaft 26 journaled therein, which shaft may be suitably driven, and contained within the housing is gearing which driven from the shaft 26 in turn drives the cutter 22.

A shuttle engaging disk 27 is mounted on a bushing 28 which is journaled in bearing 20 and is adjustably clamped thereto by aclamping screw 29. Extending through the bushing 28 is a sliding pin 30 which is manually moved by a knurled head 31 that is connected thereto. Pivotally carried by a bushing 32 which is mounted in bearing 19 is a plate 33 of a length greater than the length of the shuttle, the bushing 32 being held in adjusted position by means of a clamp screw 34. Projecting outwardly from the rear face of the plate 33 is a perforated boss 35 through which vertically slides an arm 36 which arm is adjustably held in the boss by a set screw 37, the lower end of the arm 36 being formed of U-shape so as to provide a stop 38 which projects on the front face of plate 33. A similar stop mechanism is provided at the opposite end of the plate 33 at 39. Similarly an end stop 40 is adjustable on a rod 43 which rod is attached to the plate 33 by a lug 4: 1. The plate 33 is further provided with an adjustable leg 41 which at its lower end rests 011 a projection 422 that is in suitable rigid connection with the holder 18, the leg 41 being for the purpose of supporting and steadying the plate 33 in horizontal position.

In operation the bottom of the shuttle is engaged by the stops 38 and 39, and one end of the shuttle is engaged by the end stop 40,

whereupon the plate 33 and the disk 27 are adjusted so as to center the shuttle or the block of wood from which the shuttle is being formed, relative to the cutter 22, to bring the front end of the cutter closely adjacent to the wall I) of the shuttle opening 0, the pin 30 having been previously inserted through a hole H, provided therefor in the block. The post 5 is then depressed until the stop collar lengages the upper face of the bearing 11, whereupon pressure is placed on the plate 33 and the shuttle by the hands of the operator to move the plate carrying the leg 41 downward until the leg 41 engages projection 42, which latter move ment, causes plate 33 and the shuttle, to move to a horizontal plane determined by adjustment of leg 41 after which the shuttle is manually raised to a vertical position on the pivot pin 30 causing the cutter to act on the shuttle so as to round same at a, whereupon pressure is released on the treadle, which causes the spring 17 to raise the post 5 up to normal position, whereupon the pin 30 is released,and the operation is completed. The cutter 22 and the contracted upper or top portion of the housing 21 are received in the usual channeled portion 0 which portion is formed in the block prior to the latter being subjected to the action of the present invention, the channeled portion 0 being common to all shuttles. It will also be understood that the shuttle block is held in being operated upon, with its top face or side down, so that the cutter acts beneath the block, the latter being placed in overlying relation to the cutter and above same.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1 In a machine of the type set forth, a vertically adjustable knee, a cross slide carried by the knee, a base plate vertically movable relative to and supported by the cross slide, a U-shaped springbetween the base plate and the cross slide, means to depress the base plate against the action of the spring, a head on the base plate, a disk and a pin movably supported by the head to engage the shuttle, a plate also adjustably carried by the head, said plate having ad justable stops thereon to engage the bottom and an end of the shuttle, a cutter disposed in the space between the plate and disk, :1. leg depending from the plate, and a stop to engage the leg to thereby hold the plate in horizontal position.

2. In a shuttle cutting machine, a cutter, a shuttle holder arranged adjacent to the cutter, means to engage the shuttle to allow the latter to have pivotal movement there about, whereby the shuttle may be moved from a horizontal to a vertical position, means to support the holder and shuttle engaging means whereby the same may have vertical movement, and means to lower said supporting means.
